Answer: $4.50
Step-by-step explanation:
125=21.50+23x
This is the equation to find this situation since 125 was given and it equals the left over and the spent money.
Subtract 21.50 from both sides first to be epic.
103.5=23x
Very cool! Divide both sides by 23 to get 4.5=x

Answer: the z score is 1
Step-by-step explanation:
Since the head circumference for boys at birth is normally distributed,
we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = head circumference for boys at birth.
µ = mean head circumference
σ = standard deviation
From the information given,
µ = 34.5cm
σ = 1.3 cm
For a boy born with a head circumference of 35.8cm, the z score is
z = (35.8 - 34.5)/1.3
z = 1
